what is the difference between reverse, in n out swing??? how do u do the 3 different types of swing??

Answer 1

Reverse Swing-Once the ball becomes older and more worn, it will begin to move in the opposite direction to where it would usually swing with no great change in the bowling grip.

For example, an outswinger's grip will move towards the batsman in the air while an inswinger will move away from the bat. All this tends to happen very late on in the delivery, making it difficult for the batsman to pick up the changes in the air. Not every single bowler can obtain reverse swing - the ball needs to be propelled above 80mph or thereabouts to make it move in the air

Inswing-An inswinger is bowled by holding the cricket ball with the seam vertical and the first two fingers slightly across the seam so that it is angled a little to the leg side. Once the ball has worn and been polished so that one side is rougher than the other, the rough side is placed on the leg side. The ball is placed on the pad of the thumb. This thumb position locks the wrist in a position inclined to the leg side.

Outswing-An outswinger is bowled by holding the cricket ball with the seam vertical and the first two fingers running along either side of the seam. Once the ball has worn and been polished so that one side is rougher than the other, the rough side is placed on the left (as seen from the bowler's viewpoint). When the bowler delivers the ball, he angles the seam so that it points slightly to the left as well, and releases the ball rotating about a horizontal axis with the seam along the rotational "equator". The angle of the seam to the direction of motion produces an aerofoil effect as the ball moves through the air, pushing it to the left. This is enhanced by differential air pressure caused by movement of air over the rough and smooth surfaces, which also tends to push the ball to the left. The result is that the ball curves, or swings to the left.

From a right-handed batsman's point of view, the swing is away from his body towards the right, i.e. towards the off side. This swing away from the body is the source of the name outswinger. To a left-handed batsman, the swing is in towards the body and towards the leg side.

Inswing can be bowled from side-on, mid-way or chest on positions. It is the wrist position that is crucial, not the position of hips or shoulders

The result is that the ball curves, or swings to the left.

When the ball becomes very old—around 40 or more overs old, it can begin to swing towards the polished side rather than the rough side. This is known as reverse swing . In essence, both sides have turbulent flow, but here the seam causes the airflow to separate earlier on one side. The result is always a swing to the side with the later separation, so the swing is away from the seam.
